From the back of the book:
No More Room In Hell - Surviving the Zombie Apocalypse allows you to create a group of characters amidst the end of the living world...and the start of the living-dead world. Who will survive? Who will feed the Zeds? It's up to you to select the skills, the traits and the gear that you think that your survivors will need to face the rising zombie tide.
Featuring a campaign system, stand-alone games, random scenario, and quick-play random character generation, anything goes. You'll need to fight the dead and the living as you struggle to gather enough food, ammunition and food for your band.
